Type 0: Definition of Default Values

Use

If a planned or target value is available for an input value, you can enter the planned or target value as a default value in the process instruction.

If you have defined default values for one or several input values, these default values are displayed in the corresponding input fields when you access the browser-based PI sheet or the process manufacturing cockpit . You can change these default values.

Features

You can enter a default value as follows in the process instruction:

As a constant value if it has already been specified in the process order or the cockpit definition
As a variable if it is only available in the PI sheet or cockpit

You can define constant default values as follows:

As a numerical value
The data type of the characteristic that you want to request must then also be numerical.
As an alphanumerical value
As message characteristics

If you use a message characteristic to define constant default values, you can proceed as follows:

You can enter the required default value manually.
You can let the system assign the default value automatically. However, you can only use this option, if the settings required for automatic value assignment are made for the message characteristic in Customizing; see Process Instructions: Automatic Characteristic Value Assignment .

Example Example

Message category PI_PROD is assigned to a process data request. The following characteristics have been maintained in the process instruction for the input value Product quantity .

End of the example.

Number	Characteristics	Value
0070	PPPI_INPUT_REQUEST	Product quantity:
0080	PPPI_MATERIAL_PRODUCED
0090	PPPI_REQUESTED_VALUE	PPPI_MATERIAL_PRODUCED

Characteristic PPPI_MATERIAL_PRODUCED is defined as an input value in number 0090. In number 0080, this characteristic is used to define a constant default value for the input value. Since the planned order quantity is automatically assigned as the characteristic value, the planned value is proposed in the PI sheet.

You define variables as default values if you want to transfer the default value from another process instruction of the same process order or cockpit.

Activities

You define constant default values in the process instruction by assigning one of the following characteristics after characteristic PPPI_INPUT_REQUEST:

Characteristic

Meaning

Value

< PPPI_DEFAULT_VALUE or

< PPPI_DEFAULT_STRING or

< <Any message characteristic>

< Numerical default value

< Alphanumerical default value

< Any message characteristic

< Numerical value

< Alphanumerical value

< According to characteristic definition, may also be automatically

You define variable as the default value in the process instruction by assigning the following characteristic after characteristic PPPI_INPUT_REQUEST:

Characteristic	Meaning	Value
PPPI_DEFAULT_VARIABLE	Variable as a default value	Variable name
